The Deptford Marbles [or Deptfort Marbles as the accompanying sign calls them] is a mural that greets travellers passing the foot of Tanner's Hill on their way into New Cross.

Combining the mystery and awe of the Monolith with the haphazardness of a game of Jenga at The Royal Albert, it was created by prolific local team Artmongers in 2007 and incorporates three of the wall's buttresses into the image.
